Methods and apparatus for patient care detect a current medical condition of a patient receiving medical treatment, e.g., by sensing blood pressure, heart rate, weight, glucose level, hemoglobin level, and / or blood potassium level (all by way of example) and transmit information regarding that medical condition to a digital data processing system disposed remotely from the medical treatment apparatus. The medical treatment apparatus can be, for example, one for peritoneal dialysis and hemodialysis, and the medical condition can be sensed by sensors coupled to or otherwise utilized in connection with such apparatus.
